Abstract: The present invention aims to control position of flying object with respect to a structural object in a situation where it is difficult to perform positioning based on radio signals transmitted from a satellite. A position identification unit identifies position of flying object in troublesome GPS signal reception space, using different methods for coordinate axes. Specifically, position identification unit identifies position, on Z axis (first coordinate axis), of flying object in troublesome GPS signal reception space, based on distance from flying object to structural object (distance measured at time of position identification), and identifies positions, on X and Y axes (second coordinate axes), of flying object based on change in shape of structural object in respective axis directions of X and Y axes (second coordinate axes) (history of distance from flying object to bridge B measured multiple times until position identification).
